Hi Tryffel
First of all go to the dashboard->setting->permalink and click on save changes and just have a look whether it works or not.
If this doesnot works then deactivate the plugin one by one which you have installed and check it.
If still not working then send your temporary username and password. we will look on it.
For the footer text you just add this css inside
dashboard-> apperance->theme-option-> design Options-> Custum CSS
#site-generator .copyright {
text-align: center;
}
thank you
Sunil
